Coye and I have had our short paper accepted to CSCW 2010, and nominated for best note award, which is exciting:

Antin, J., and C. Cheshire. 2010. “Readers are not Free-Riders: Reading as a Form of Participation on Wikipedia.” in Proceedings of the ACM 2009 conference on Computer supported cooperative work. Savannah, GA. (PDF)

You can check out the full advance program too. Looks like lots of fantastic papers in there!
